Currently the only methods to investigate traumatic brain injury (TBI) include post mortem analysis, high volume rat studies, and static CT, MRI, or brain visualization of a brain already experiencing TBI. LLNL is working to conduct the world’s first study of the actual mechanism of TBI using dynamic radiography. In a first step, rudimentary brain structures and contrast agents have been examined that would be used for static radiography tests. The project includes the design of the brain phantom used for the dynamic CT test and the design of the elastic impactor. Phantom and impactor will be fabricated, tested, and then the X-ray radiographs will have to be analyzed. The setup must fit within the bounds of a flash X-ray system. A photo of the Army Research Lab’s 3-ring flash X-ray system is shown below for reference.
